+244 A wind farm generator uses a four-bladed propeller mounted on a pylon at a height of 15 m, as shown in the figure. The width of the pylon is very narrow, and the length of each propeller blade is 5 m. A tip of the propeller breaks off just when the propeller is vertical as shown in figure. The fragment flies off horizontally, falls, and strikes the ground at a distance P from the base with negligible air resistance. Just before the fragment broke off, the propeller was turning uniformly, taking 1.2 s for each rotation. How long is the distance P?
A.13 m
B.92 m
C.36 m
D.107 m
E.120 m
